Hot Bike's 2026 Motor Bike Expo Pick

There are custom motorcycles—and then there are motorcycles that transcend the label entirely.

Swiss builder Stéphane Grand of T4 Motor-Cycles has created something that blurs the line between vintage Harley-Davidson, mechanical sculpture, and engineering experiment. Starting with a genuine 1949 Harley-Davidson FL Panhead, Grand spent roughly 3,500 hours transforming one of Milwaukee's most iconic V-twins into a rolling work of art built almost entirely by hand.

Even more impressive? Every component was crafted using traditional machine tools and old-world fabrication techniques. There was no CNC machining, no CAD software, and no computer-controlled manufacturing. Just decades of craftsmanship, patience, and imagination.

For those reasons alone, this remarkable machine earned Hot Bike's Pick of the 2026 Motor Bike Expo.

A Panhead Unlike Any Other

Rather than restoring history, Grand chose to reinterpret it.

The foundation remains an authentic 1949 FL Panhead, but nearly everything surrounding the original engine has been reimagined. The bike's most recognizable feature is its stunning twisted steel frame, forged entirely by hand using traditional torch techniques.

Each twist was individually heated, shaped, polished, and eventually chrome-plated, creating a flowing structure unlike anything seen in the Harley world.

Ironically, the chrome nearly ended the project.

After an unsuccessful first plating attempt, Grand was forced to completely strip the frame, re-polish every surface, and start the finishing process again. The extra work paid off, resulting in a flawless liquid-chrome finish that highlights every handcrafted detail.

Traditional Craftsmanship Meets Radical Engineering

The handcrafted frame supports a completely fabricated front suspension featuring a custom 40-centimeter fork and one-off triple trees.

The rear suspension is equally inventive. Instead of relying on conventional springs beneath the stainless steel seat, Grand designed a hidden pneumatic suspension system with electrically controlled air cylinders. The result is a rigid-looking motorcycle that still offers surprising ride quality—despite having no foam or leather padding whatsoever.

A Supercharged 1949 Panhead

While the motorcycle appears vintage, its engine is anything but stock.

Grand retained the original 1949 Panhead cases, cylinders, and heads but extensively modified the internals. Custom pistons work alongside an adapted Chevrolet crankshaft fitted inside the original Harley cases, increasing displacement to approximately 1,300cc.

Fuel is delivered through a classic SU carburetor, but the real surprise is hiding beside it.

Grand engineered a completely custom supercharger system using a jet ski blower, designing the intake and drive system from scratch before integrating everything directly into the original Harley four-speed transmission.

It's an ambitious piece of engineering rarely seen on vintage American V-twins.

One of Grand's favorite details is the fully hand-built stainless steel exhaust system, whose flowing bends weave naturally through the twisted chassis while functioning as both sculpture and performance component.

Every Detail Built by Hand

Nothing on the motorcycle escaped customization.

The original Harley four-speed transmission was reshaped before being entirely hand engraved by master engraver Bruno Zamit. The clutch and primary drive are also one-off creations.

Both 21-inch wheels feature reverse-laced spokes with polished brass inserts, while braking duties are intentionally minimalist.

There's no front brake.

Stopping power comes solely from a modified 1958 Harley-Davidson Duo Glide rear drum brake.

The stainless steel fuel tank may be the most complicated component on the motorcycle. It doubles as the oil reservoir while incorporating side windows that allow the rider to visually monitor fuel level—a functional centerpiece worthy of the surrounding craftsmanship.

Bronze, Gold Leaf, and Mechanical Art

The finishing touches elevate the motorcycle from impressive fabrication to rolling artwork.

Painter Stéphanie Dutruel of Atelier Allégoria layered bronze paint over genuine gold leaf before adding intricate gear-inspired graphics that shift dramatically depending on lighting and viewing angle.

Chrome-plated structural components contrast beautifully with polished stainless steel and aluminum throughout the motorcycle.

Lighting follows the same philosophy.

The headlight began life as an early-1900s carriage oil lamp before being converted to electric while preserving its antique appearance. A tiny LED taillight hides near the swingarm, while gauges, turn signals, front fender, and even the license plate mount have all been omitted in pursuit of visual purity.

Built Purely for the Love of Creating

Unlike many award-winning customs, this Panhead wasn't built to chase trophies or customers.

Grand says the project began simply for the pleasure of building.

The original concept came to him while relaxing beside a swimming pool during a vacation in Italy, where he first sketched the unique front fork that would ultimately define the motorcycle.

Since opening T4 Motor-Cycles in 2009, Grand has completed five full custom motorcycles while balancing customer builds with personal passion projects.

His SG4 earned multiple Best of Show awards during the 2019 Sturgis Rally, and his return in 2024 brought recognition from many of the industry's biggest names—including Billy Lane, whose praise remains one of Grand's proudest moments.

Still, Grand admits one regret remains.

He wishes legendary builder Indian Larry had lived long enough to see his work.

Looking at this extraordinary Panhead, it's easy to imagine Larry appreciating every hand-forged detail.

In an era dominated by computer modeling and digital manufacturing, Stéphane Grand reminds us that some of the world's most extraordinary motorcycles are still built the old-fashioned way—with fire, steel, patience, and an unwavering vision.
